All-In-One Ruggedized 5GT/s 2:1/1:2 PCIe Mux and
Redriver with Equalization
Electrical Characteristics (continued)
(V_CC = +3.0V to +3.6V, C_CL = 75nF coupling capacitor on each output, R_L = 50I on each output, T_A = -40°C to +85°C, unless other-
wise noted. Typical values are at V_CC = +3.3V and T_A = +25°C.) (Note 3)
